The first step is the light dependent reaction. In this step, energy from the sun is collected by the chlorophyll and converted for use by the plant.
Next, H2O is split and an electron is sent through photosystem 2. The spliting of H2O releases oxygen. Here, it gets energized. As the electron travels, it loses energy. Because of this, the electron enters photosystem 1 to be re-energized. After that, it then keeps traveling and makes NADPH and ATP.
The carbon goes around and makes ADP and NHDP+. These molecules can go back in the thylakoid to help with the light dependent reaction. It also creates G3P and rubisco. The G3P is sent out to make glucose and rubisco. Rubisco then is used to make RuBP, which is the starting point of the Calvin Cycle.
